UNITED STATES PATENT JACOB COLOGNATI, OF 'NElV YORK, N. Y., ASSIGNOR TO JOSEPH LUROl-, OF SAME PLACE.

SHOVEL.

SPECIFICATION forming part of Letters Patent N o. 645,348, dated March 13, 1900.-

Application filed J'nly 20, 1899. Serial No. 724,532. (No mollelz) To @ZZ whom, t Hefty conceive:

Be it known that I, JACOB COLOGNATI, a subject of the Emperor of Austria-Hungary, residing at New York, (Brooklyn,) in the county of Kings and State of NewYork, have invented new and useful Improvements in Shovels, of which the following is a specifi- Fig. is a section along x ,-Fig. 2, showingy the slide in position to free the tool or blade. Fig. 6 is a section along y y, Fig. 4, the slide being in position to lock the blade. Fig. 7 is a section along a a, Fig. 4. Fig. 8 is a sectional side elevation of a modification. Fig. 9 is a frontelevation of Fig. 8. Fig. 10 is a rear elevation of Fig. 9. Fig. 11 is a section along w w, Fig. 9. I

The shovel-blade 1 has oppositely-located reinforcing- plates 2 and 3, riveted to one another and to the blade. The rivets are shown at 4. One of the plates is bent or anged about the other plate and about the blade, as seen at 5. The plates have handle-extension or sleeve sections 6, which together form a tube for engaging and securing the handle or stem 7. On the handle is a sleeve 8, the two being connected by what may be called a bayonet-joint for allowing the sleeve to be rotated on and moved along the handle or stem 7. The stem is shown with slot or way 9, having lateral branches 9' at its opposite ends, and the sleeve has a stud or pin 10. When the pin 10 is in the main branch 9, the sleeve S can slide or move longitudinally. lVhen this sleeve is rotated to carry pin 10 into a lateral branch 9', the sleeve is held against sliding. A catch or spring 11, Figs. 3 and 4, can lock the sleeve. This catch can be readily made on the plan of the trigger or thumb-spring of umbrellas, so as to be capable of being pressed back out of action or to release position. As shown, this catch has a nose 11', specially arranged for enabling the thumb to press the catch to release. The sleeve has eyes or catch parts 14 and 15.

fWhen the catch 11 engages into the eye 14,

the pin 10 is locked in the lower lateral groove branch 9. On the catch releasing eye 14 the sleeve can be rotated to bring pin 10 to the main channel 9, whereupon eye l5 is caught by catch l1. This catch must now be again released before the sleeve 8 can be run along stem 7. When thus run along the stem 7, the sleeve 8 practically lengthens this stem or forms an extension thereof to secure proper length for working. lVhen extended, the sleeve 8 can-turn or run its pin 10 into the upper lateral channel branch. A catch 16 on the plan of catch 11 can be applied to engage eyes 14 or 15 when the sleeve is extended.

The handle or stem 7 is hollow to receive a blade or tool, such as a saw 17. This tool has an eye or handle 18, which is always in reach or projecting from the sleeve 8, so that the tool can be slid or extended out of the sleeve for Working or sheathed in the sleeve when not to be used. This tool, while slidable, cannot be entirely withdrawn from the sleeve, a shoulder or enlargement 19 preventing the tool being entirely Withdrawn. This tool can thus not be separated from the shovel and is secure against loss or misplacement.

In addition to shoulder 19 the blade 17 has the two shoulders or edges 20 and 21. The sleeve 8 has in its top, Figsf and 6, an opening' comprising the part 23 with the enlargement or extended branches 24. Say the blade 17 is housed in the sleeve and the latter has pin 10 in a lateral channel branch 9 and eye 14 engaged by catch 11 or 16. The opening part 23 now rests at shoulders 20, and as this l part 23 is of smaller diameter the shoulders 20 or blade 17 cannot slide out of the sleeve S and is securely sheathed or inoperative. On rotating the sleeve 8, as indicated by arrow 31, Fig. 6, to bring pin 19 to channel branch 9 the enlarged opening portion 24 is brought to register with the blade 17 or with shoulder 20, Fig. 5, to enable the blade to be ICO drawn out to exposed or Working position. By then giving sleeve S another suitable turn in -the direction of arrow 32, Fig. 5, the smaller opening part 23 is broughtunder or against shoulder 2l, Fig. 4, to lock the blade against slipping back out of operative position into the locking-sleeve. The blade can thus by its opposite shoulders 2O and 2l be locked in housed or in Working position, as desired, and such blade can be utilized or housed either when the sleeve is locked by catch or spring 16 in extended or by catch or spring ll in closed position, as desired.

When the device is contracted or closed up, itis conveniently carried and is thus practical for use by troops and can be carried by the men or in Wagons, as seen fit. When to be carried by a man, a carrier enabling the shovel tobe snapped or removably connected to the belt is practical. Such a carrier is readily formed by a trough-shaped rim 28, Figs. 8 to 10, consisting of a strip of leather or the like suitably bent and doubled and reinforced at the outer edge by a strip of metal 29. The shovel-blade 1 can have its front and lateral edges slipped into trough 2S and then secured by holding-straps 30, secured to the carrier. These straps being run about the back edge of the shovel and then secured at their free ends by buttons or fastenings 25 on the carrier, the shovel-blade and carrier are secured together. The carrier 28 is shown with a snap or spring hook 26, so that it can be readily connected to or taken from a belt or a ring or like attachment 27, suitably connected to a belt. (Not shown.)

The device can be modified. In place of having the sleeve 8 rotatable and slidable, said sleeve can be merely rotatable, as shown by sleeve 8', Figs. S to l1. Aslidable sleeve is thought, however, to be of advantage, as it ,enables the shaft 7 to be practically lengthened and shortened, as the extended sleeve 8 forms in reality a continuation of the shaft. The sleeve 8', like the sleeve 8, has a pin- andslot connection 10 and 9; but the channel branch 9 is not required for a non-sliding sleeve, such as 8. As seen in Fig. 11, when catch 16 engages eye 14 the rim 23 of cut 23 24: locks the blade in sheathed position. A quarter-turn of sleeve 8', as indicated by arrow, Fig. 1l, brings the Wide slot part 24 to register with the blade, so that the latter can be slid to exposed or working position, and the catch 16 then engages eye 15, Fig. l1, of sleeve S'.

ders made to be engaged by the sleeve to lock Athe tool in operative or in inoperative position substantially as described.

2. A shovel having a hollowed handle provided With a rotary locking-sleeve, a sliding tool in the handle having opposite shoulders for engaging the sleeve, and a catch or spring for locking the sleeve substantially as described.

3. A shovel having a hollowed handle provided with a rotary locking-sleeve, and a sliding tool in the handle having opposite shoulders for engaging the sleeve, said sleeve being slidably mounted on the handle to form an extension substantially as described.

4. Ashovel having a hollowed handle provided With a rotary and sliding rocking sleeve, a sliding tool having opposite shoulders for engaging the sleeve, and catches or springs for locking the sleeve in extended 4and closed position substantially as described.

5. 'A shovel having a holloWed handle provided With a rotary locking-sleeve, a sliding tool having opposite locking-shoulders made to be` engaged by the sleeve, and a carrier for said shovel comprising a trough-shaped rim 28 and releasable holding-strap, said carrier having a snap hook or attachment for connecting to a belt or the like substantially as described.

6. A shovel having a hollowed handle provided With a rotary locking-sleeve, and a sliding tool having locking-shoulders made to be engaged by the sleeve, said sleeve and handle being connected by a bayonet-joint for allowing the sleeve to be rotated and moved along the handle substantially as described.

7 A shovel-blade having oppositely-located reinforcing-plates riveted to one another and to the blade, one of the plates being bent about the other plate and the blade and said plates having handle extensions 6 substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
